How to claim the ether.fi referral bonus
- Open the referral link before creating an account.
- Create your ether.fi Cash account and complete identity verification.
- Fund the account and activate a virtual or physical card.
- Spend on the card. Campaign cashback accrues on qualifying purchases.
The catch
The headline rate is promotional. Boosted cashback offers run for limited windows and often apply only to set categories such as dining or groceries.
Abuse rules are strict. ether.fi states that gaming the program can lead to a ban and loss of rewards.
Regional limits apply. Promotions are not available in every jurisdiction.
Who should use it
ether.fi Cash fits crypto holders who want to spend against their holdings without selling to a bank account first. Anyone looking for a simple fiat debit card with no crypto exposure is better served elsewhere.
FAQ
What is the ether.fi referral code?
The ether.fi referral code is 3aba3fd1, applied when you sign up for ether.fi Cash through the referral link. New users become eligible for the current referral campaign, typically boosted cashback, and the referrer earns cashback on the new user's card spending.
How does the ether.fi referral program work?
A new user signs up for ether.fi Cash through a referral link, completes KYC and activates the card. The referrer then earns cashback based on that user's card spending, while the new user receives whatever promotional cashback the live campaign offers.
Do I need a referral code to get an ether.fi Cash card?
No. Anyone eligible can sign up directly. Signing up without a referral link, however, means missing any referral-specific campaign boost, and past promotions have offered referred users a higher cashback rate than direct sign-ups. Use a link before you create the account, because it cannot be added later.
